摘要
为定量化的研究高速公路交通安全设施保养费用及其影响因素,结合陕西省内10条高速公路,利用SPSS软件对交通安全设施影响因素进行了多元回归分析,根据确定的影响因素建立基于量价合一的交通安全设施小修保养费用模型,并对模型进行验证.结果表明:交通安全设施小修保养费用的影响因素是地区因素、通车年限和标准轴载的累计当量轴次(∑ESAL),得出的费用模型预测值与实际值高度相关,统计意义显著.
In order to quantitatively study the maintenance cost of highway traffic safety facilities and its influencing factors,combined with 10 expressways in Shaanxi Province,SPSS software was used to analyze the influencing factors of traffic safety facilities.According to the determined influencing factors,a traffic safety facility minor repair and maintenance cost model based on the combination of quantity and price was established and verified.The results show that the influencing factors of minor repair and maintenance cost of traffic safety facilities are regional factors,service life and cumulative equivalent axle times of standard axle load(∑ESAL),and the predicted value of the cost model is highly correlated with the actual value,with significant statistical significance.
